He has battled cancer and celebrates his 82nd birthday this week but Perry McKay is still fighting fit.
The great-grandad-of-14 squeezes in four training sessions a week and has converted his garage into a gym.
Perry, who celebrated his diamond wedding anniversary with his wife Joyce on Saturday, keeps his ticker in good order by walking up and down Brockholes Brow up to six times a day.
He says: “I used to do a lot of jogging but I had an operation a few years ago and had to stop.”
The former BT engineer has always taken fitness seriously and still works out every other day.
He completes a 90-minute workout with weights and a punchbag and uses his stairs at home for cardiovascular fitness.
The father-of-three says: “My two sons, Alan and Ian, when they were quite young, started to box between themselves so I bought them all the gear.
“I bought them punchbags and gloves. Over 30 years we have got a full set of weights set up in the garage.
“I walk up and down the stairs for 45 to 60 minutes every other day. I do the stair work barefoot or we’d need to replace the carpet every couple of weeks.
“Recently I’ve substituted the running and stair work for walking. People think I’m a raving lunatic. I don’t get anything out of walking on the flat so I go up and down Brockholes Brow.
“At the moment I only go up and down a couple of times each time but sometimes it will be five or six times.”
As a young man, Perry, who lives in Glenluce Drive, Farringdon Park, spent three years in the Army, serving with the Royal Electrical and Mechanical Engineers.
He says: “I was with a lot of lads who were fantastic. I was in the canal zone for two years and that is probably where I started with all the fitness.”
Perry’s wife Joyce, 81, said: “I am very very proud of my husband. He has always been interested in the children. He has never gone out and left them at night. He has always looked after them and has got them training too.”
